Statistical Analysis of Ground Water Contamination at the Alert Apron and Northern Landfill Areas of Wurtsmith AFB, Michigan

摘要

Two plumes of contamination are analyzed to determine their extent, composition, and movement. The large number of ground water monitoring wells sampled over the past eight years at Wurtsmith AFB allow us to perform this analysis directly from empirical data, with minimal assumptions about solute transport mechanisms. Conclusions are drawn about the likely sources of contamination in the two plumes, the adequacy of the data for making risk assessments, and the likely consequences of alternative programs of remediation.
